Black Box Async RS232 Extender over CATx - DB9 with Control Signals to Terminal Block ME890A-R2

Description :

Black Box Async RS232 Extender over CATx - DB9 with Control Signals to Terminal Block

• Use long-distance CATx links to communicate with serial devices.
• Control presentations remotely.
• Transfer data between computers.
• Ideal for a wide variety of applications.
• Optical isolated.
• Maximum speed of 250 K.
• Easy installation. The driver provides full-duplex transmission and hardware handshake signals. There's no need for setup or configuration.

These CATx Line Drivers enable the user to place a receiving device up to 4000 feet away from the sending device. The local unit has a DB9 female connector and is configured as a DCE device; the remote unit has a DB9 male connector and is configured as a DTE device. This allows the local/remote pair to function as a long extension cable between two RS-232 devices. There are no user-configurable settings. These units pass TXD, RXD, RTS, and CTS signals to allow application to use hardware handshake signals if neccessary.

• Plug-and-play! The driver is a pure hardware solution providing real-time data transfer with no software conflicts.


• Run data and handshake signals over CATx cable and break the RS-232 distance limitation.


• Maximum speed of 250 K.


• Supports distances up to 4000 feet.


• Has 1000-VDC isolation between CATx and RS-232 interfaces.


• Optical isolated.
